cascade temp controller disabled for 2 weeks.

Dear all.
Jim helped us open and clean the chuck. The condensation stains and corrosion dust was visible and wiped.
To further troubleshoot the problem, the temperature measurements are disabled. We have to monitor the problem - leakage and bad CVs.
Please let me know if you have questions and please post your feedback if you observe weird CVs or stray leakage.
RT measurements are fine to do.
thanks
